It is associated with authentication center (AuC) comprising the authentication data different because of subscriber.When receiving the calling to particular UE, GMSC
214 inquiry HLR 215 are transmitted to the specific MSC of the service position to determine the position of the UE and by the calling.
The core net 204 explained also uses Serving GPRS Support Node (SGSN) 218 and Gateway GPRS Support Node
(GGSN) 220 packet switched data service is supported.General Packet Radio Service (GPRS) is designed to than preferred circuit
The higher speed of the available speed of data service is exchanged to provide packet data service.GGSN 220 be UTRAN 202 provide with
The connection of packet-based network 222.Packet-based network 222 can be internet, proprietary data net or other certain conjunctions
Suitable packet-based network.The major function of GGSN 220 is to provide packet-based network connectivty to UE 210.Number
It can be transmitted between GGSN 220 and UE 210 by SGSN 218 according to grouping, the SGSN 218 is main in packet-based domain
Execute function identical with the function that MSC 212 is executed in the circuit switched domain.
In wireless telecommunication systems, concrete application is depended on, communication protocol architecture can take various forms.For example,
In 3GPP UMTS system, signaling protocol stack is divided into non-access stratum (NAS) and access stratum (AS).NAS is provided on each
Layer for the signaling between UE 210 and core net 204 (referring to Fig. 2), and may include circuit switching and packet switching protocol.
AS provides lower level, for the signaling between UTRAN 202 and UE 210, and may include user face and control plane.Here, with
Family face or i.e. data surface carry user's traffic, and control plane carries control information (that is, signaling).
Go to Fig. 3, AS is shown to have three layers: layer 1, layer 2 and layer 3.Layer 1 is lowermost layer and realizes various physical layer signals
Processing function.Layer 1 will be referred to as physical layer 306 herein.Referred to as the data link layer of layer 2 308 is on physical layer 306
And it is responsible for the link between UE 210 and B node 208 on physical layer 306.
In layer 3, rrc layer 316 disposes the control plane signaling between UE 210 and B node 208.Rrc layer 316 includes being used for road
By higher message, several function of disposition broadcast and paging function, foundation and configuration radio bearer, physical channel etc.
It can entity.
In the air interface explained, L2 layer 308 is split into each sublayer.In control plane, L2 layer 308 includes two sons
Layer: media access control (MAC) sublayer 310 and radio link control (RLC) sublayer 312.In user face, L2 layer 308 is in addition
Including Packet Data Convergence Protocol (PDCP) sublayer 314.Although being not shown, UE can have on several on L2 layer 308
Layer, including be terminated in network side the network layer (for example, IP layers) of PDN Gateway and be terminated at connection the other end (for example,
Distal end UE, server etc.) at application layer.
PDCP sublayer 314 provides the multiplexing between different radio carrying and logic channel.PDCP sublayer 314 also provides pair
The header-compressed of upper layer data packet provides safety by encrypting data grouping to reduce wireless radio transmission expense,
And the switching provided to UE between each B node is supported.
Rlc sublayer 312 generally support for data transmitting acknowledgement mode (AM) (wherein acknowledgement and retransmission processes can by with
In error correction), not acknowledgement mode (UM) and transparent mode, and provide the Segmentation and Reassembly to upper layer data packet and logarithm
According to the rearrangement of grouping to compensate mixed automatic repeat request (HARQ) at as MAC layer and caused by disorder reception.?
In acknowledgement mode, the commutative various rlc protocol data cells (PDU) of RLC peer-entities (RNC and UE etc.), including RLC number
According to PDU, RLC status PDU and RLC reset PDU, etc..In the disclosure, term " grouping " can refer to real in each RLC equity
Any RLC PDU exchanged between body.
Media access control sublayer 310 provides the multiplexing between logic channel and transmission channel.Media access control sublayer 310 is also responsible for dividing between each UE
With the various radio resources (for example, resource block) in a cellular cell.Media access control sublayer 310 is also responsible for HARQ operation.
Fig. 4 is the state diagram for explaining the operation mode of the UE 210 in UMTS network 200 for example as described above.UE 210
Two basic manipulation modes be idle mode and connection model.Connection model can be further divided into several service states,
These service states define UE 210 and what kind of physical channel are used.Fig. 4 shows the main RRC in connection model
Service state.Also show the transformation between idle mode 400 and connection model 402 and the possible transition in connection model.
In idle mode 400, UE 210 can receive system information and cellular cell broadcast (CB) message.UE 210 is maintained at idle
Mode 400 establishes the request of RRC connection until its transmission.In idle mode 400, UTRAN 202 does not have the pass of their own
In the information of each idle mode UE, and all UE in such as cellular cell can only be addressed or monitor the institute of paging occasion
There is UE.
In connection model 402, UE 210 can be at Cell_DCH (cellular cell _ DCH) state 404, Cell_FACH shape
One of state 406, Cell PCH (cellular cell PCH) _ state 408 and utran registration area_paging indicator channel state 410.In Cell_DCH state 404,
Dedicated physical channel is assigned to UE 210, and the UE 210 on cellular cell or active set rank known to its Serving RNC.
It is not 210 dedicated physical channels allocated of UE in Cell_FACH state 406, but transfers to use random access channel
(RACH) and forward access channel (FACH), for transmitting both signaling message and a small amount of user face data.UE is in Cell_FACH
Power consumption in state 406 is usually more low in energy consumption than Cell_DCH state 404.
In Cell_PCH state 410, UE 210 is still known in the cellular cell rank in Serving RNC (SRNC)
, but it can only be reached via paging channel (PCH).In this state, the battery consumption ratio Cell_DCH state 404 of UE
And/or Cell_FACH state 406 is less, because including discontinuous reception (DRX) functionality to the monitoring of PCH.If UE 210
Cell reselection is executed, then to execute cellular cell Regeneration rules, hereafter such as it automatically moves to Cell_FACH state 406
Fruit does not trigger other activities during the Regeneration rules of cellular cell, then UE 210 reenters Cell_PCH state 410.If from
Another radio access system selects new cellular cell, then RRC state is changed to idle mode 400, and to another system
The access of system is executed according to the specification of the system.
Utran registration area_paging indicator channel state 410 is very similar to Cell_PCH state 408, the difference is that UE 210 is not in each bee
Cellular cell is executed after nest cell reselection to update, but transfers to read UTRAN registration area (URA) identity from BCH, and
And only in the case where URA changes (after cell reselection), 210 ability of UE to SRNC notifies its position.UE 210 exists
Power consumption in utran registration area_paging indicator channel state 410 is usually less than the power consumption in Cell_DCH state 404 and/or Cell_FACH state 406.
UE 210 leaves connection model when RRC connection is released or occurs RRC connecting fault and returns to idle mode
400.Change UE 210 between the above state to be related to exchanging control message on a control channel.For example, UE 210 can be to
RNC 206 sends signaling connection release instruction (SCRI).Based on the value of the SCRI received, RNC 206 can order UE 210 to make
With Cell_PCH state 408 or utran registration area_paging indicator channel state 410, rather than discharges RRC and connect and UE 210 is made to fall into idle mode 400.
In another example, RNC 206 can order UE 210 to fall directly into idle mode 400 from Cell_DCH state 404.
In idle mode 400, UE 210 can be converted to Cell_DCH state 404 or Cell_FACH state 406.From sky
This transformation of not busy mode 400 is initiated by RRC connection request.The step is related to that necessary radio access bearer is arranged
(RAB).It is related to removing from the transformation of Cell_FACH state 406 or Cell_DCH state 404 to Cell_PCH state 408
The radio access bearer of distribution.Transformation from Cell_DCH state 404 to Cell_FACH state 406 is related to recalling being distributed
Power and code.When UE 210 is in Cell_DCH state 404, UE 210, which consumes energy more more than other states, to be come
Connection is set to keep effective in DCH state.
In many wireless networks (for example, UMTS), connection can be converted to Cell_FACH from Cell_DCH state 404
State 406 to reduce power consumption under given conditions, but the data throughout in Cell_FACH state 406 is lower than Cell_DCH
Data throughout in state 404.However, the amount of energy needed for the side UE may be still a large amount of in Cell_FACH state 406
's.Therefore, UE 210 can be converted to the even lower state of energy consumption from Cell_DCH state 404 and Cell_FACH state 406
(such as Cell_PCH state 408, utran registration area_paging indicator channel state 410) or transform back into idle mode 400.
RRC, which reconfigures regulation, can be used for changing UE state, for example, changing from Cell_PCH state to Cell_FACH shape
State, vice versa.It includes that radio bearer is established regulation, radio bearer reconfiguration regulation, radio and held that RRC, which reconfigures regulation,
Carry release regulation, transmission channel reconfigures regulation and physical channel regulation.Physical channel regulation is used for
It establishes, reconfigure and release physical channels.
Radio bearer establishes regulation and is used to set up new radio bearer.Radio bearer reconfiguration regulation is used for
For radio bearer reconfiguration parameter.Radio bearer release regulation be used to discharge radio bearer.Transmission channel reconfigures
Regulation be used to reconfigure transport channel parameters.Physical channel regulation is used to set up, reconfigures and release physical
Channel.
3GPP specification release 7 and release 8 introduce enhanced Cell_FACH state, will pass through in Cell_FACH shape
Terminal user's performance and system effectiveness are improved using HSPA transmission and physical channel in state.(hereafter from enhanced Cell_FACH
Can be described as " Cell_FACH ") to Cell_DCH state transformation be actually it is seamless because physical channel has not been changed.?
In Cell_FACH state, E-DCH transmission channel is transmitted for uplink.It will the E-DCH used in Cell_FACH state
Resource and initial data rates distribution are broadcast to cellular cell.
UTRAN 202 is an example according to the available RAN of the disclosure.With reference to Fig. 5, as an example, not a limit,
The signal that simplifies for illustrating the RAN 500 in UTRAN framework explains.The system includes multiple cellular zones (cellular cell), packet
Include respectively may include one or more sectors cellular cell 502,504 and 506.Cellular cell can geographically define (for example,
Defined by overlay area) and/or can be defined according to frequency, scrambled code etc..That is, the honeycomb geographically defined explained
Cell 502,504 and 506 can be respectively for example by being further divided into multiple cellular cells using different scrambled codes.Example
Such as, cellular cell 504a can use the first scrambled code, and cellular cell 504b is (while in same geographical area and by same
One B node 544 services) it can by being distinguished using the second scrambled code.
In the cellular cell for being divided into sector, multiple sectors in cellular cell can be formed by each antenna groups,
Wherein each antenna is responsible for being communicated with each UE in a part of the cellular cell.For example, in cellular cell 502, day
Line-group 512,514 and 516 can respectively correspond to different sectors.In cellular cell 504, antenna groups 518,520 and 522 can be respective
Corresponding to different sectors.In cellular cell 506, antenna groups 524,526 and 528 can respectively correspond to different sectors.

The list of cellular cell is (that is, current assign downlink dedicated physical channels DPCH or part downlink chain to UE 536
The cellular cell UTRAN those of road dedicated physical channel F-DPCH may make up active set).
UTRAN air interface can be spread spectrum direct sequence CDMA (DS-CDMA) system, such as be marked using W-CDMA
Quasi- air interface.DS-CDMA is spread by the sequence of the pseudo-random bits multiplied by referred to as chip come spread user data.With
Such DS-CDMA technology is based in the W-CDMA air interface of UTRAN 202 and is also required frequency division duplex (FDD).FDD saves B
Uplink (UL) and downlink (DL) between point 208 and UE 210 use different carrier frequencies.Benefit for UMTS
It is TD-SCDMA air interface with DS-CDMA and using another air interface of time division duplex (TDD).Those skilled in the art will
Recognize, while characterized as each example may quote from W-CDMA air interface, but cardinal principle is equally applicable to TD-
SCDMA air interface or any other suitable air interface.
In one example, UE 210 is in Cell_FACH state 406, and network (for example, UTRAN 202) can
Physical channel (PCR) regulation that explains moves to Cell_PCH state in the message flow diagram that instruction UE 210 passes through Fig. 6
408.Network sends physical channel (PCR) message 602 to UE 210.In the side UE, if the PCR in downlink (DL)
Message 602 is received by the AM-RLC entity of UE, then the RLC entity will be for each DL PDU transport layer for carrying PCR message 602
2 acknowledgements (L2ACK) 612.In response to PCR message 602, the AM entity transmission physical channel of UE completes (PCRC) message
614, network sends the L2ACK 616 for being directed to the PCRC 614.In this illustration, L2ACK 612 and PCRC 614 be via
Random access channel (RACH) regulation transmits.
Once receiving L2ACK 616 at UE, it is assumed by PCRC message 614 and is received completely in RRC rank by network, and
The RRC entity of UE will be initially configured its layer 1 (L1) to move in Cell_PCH state.If reconfiguring regulation is in Cell_
It is initiated in FACH state, then L2ACK 612 is sent to network by using RACH regulation, this is based between UE and network
Radio channel condition may take different amounts of time.Therefore, there is the re-transmission (reTx) for the PDU for carrying PCR message in DL
618 be possible.Since PCRC message 614 has been considered as completely in the RRC rank of UE (that is, L2ACK 616 has been connect by UE
Receive), therefore the re-transmission of PCR PDU will be abandoned by UE.Nevertheless, UE will be directed to according to standard schedule in the related technology
The PDU 618 of the re-transmission of PCR message transmits L2ACK.
At UE, if there is any uplink RLC ACK PDU 620 co-pending (for example, being directed to PCR reTx
618 L2ACK), this be in RLC/MAC rank only it is known, then the RRC of UE will continue to configure its layer 1 to Cell_PCH state
To complete to reconfigure.After UE moves to Cell_PCH state, will there is the RLC transmitted to UL to the instruction of RRC entity in RLC entity
Data (for example, L2ACK 620).UE is moved back to Cell_FACH state via RACH regulation 622 by this by triggering RRC entity
Send RLC data co-pending.However, this scene result in from Cell_PCH state to Cell_FACH state and subsequently back into
The undesirable additional transition of Cell_PCH state.Which results in additional signaling and power dissipation overhead, not at UE, execution is any
Useful function.
Correspondingly, all aspects of this disclosure provide solution, and wherein UE can be reduced or avoid to pending uplink
The unnecessary re-transmission of RLC PDU (for example, L2ACK 620) and unnecessarily make UE between different RRC states (for example,
Between Cell_PCH state and Cell_FACH state) transformation.Therefore, power consumption and signaling overheads at UE can be reduced or avoided
And the waiting time.
In the one side of the disclosure, in the side UE, once acknowledgement PCRC message is received from network in the PCR regulation of Fig. 6
614 RLC ACK 616 then can be ignored for any into one of any DL RLC PDU for being related to completed PCR message 602
The pending uplink RLC ACK PDU (for example, L2ACK 620) of step, and the RLC buffer of the control PDU of UE can be clear
It is empty.In other words, RLC ACK PDU co-pending is cancelled or deletes at UE.In addition, in the side UE, if there is co-pending for transmitting
Any ongoing RACH regulation 622 of uplink L2ACK PDU, then the RACH regulation 622 can be aborted.
Fig. 7 is the stream for explaining the physical channel regulation 700 that can be operated at UE according to the one side of the disclosure
Cheng Tu.Regulation 700 can be operated at UE 210, and UE 210 can be implemented as the device 800 that will be described in more detail below
(referring to Fig. 8).In step 1 702, UE is related to corresponding uplink L2ACK 612 by downlink PCR message 602.That is,
UE identifies that L2ACK 612 is the success response to PCR message 602.In step 2 704, UE is by uplink PCRC message 614
It is related to the downlink L2ACK 616 of the corresponding acknowledgement PCRC message.That is, UE identifies that L2ACK 616 is disappeared to PCRC
The success response of breath 614.Step 1 702 and step 2 704 can in different order or be performed simultaneously.In step 3 706, UE is determined
It is co-pending for whether having uplink L2ACK PDU.In step 4 708, UE determine pending uplink L2ACK PDU whether be
For acknowledgement PCR message 602.In step 5 710, if L2ACK PDU co-pending, for PCR message 602, UE cancels
The L2ACK PDU (for example, L2ACK 620) co-pending.Correspondingly, related based on what is made in step 1 is to two, in step 3
It can determine to five, UE and cancel any pending uplink RLC ACK PDU for PCR message 602 (for example, L2ACK
620).Since the L2ACK 616 of acknowledgement PCRC message 614 has been properly received and has been executed by UE, L2ACK 620 co-pending is not
It is necessary and be cancelled.In some aspects of the disclosure, L2ACK 616 is referred to alternatively as the first acknowledgement, and L2ACK 612 can be claimed
For the second acknowledgement.
In step 6 712, UE determines whether uplink RACH regulation is underway.In step 7 714, UE, which is determined, to be carried out
In RACH regulation whether be uplink L2ACK PDU for retransmitting acknowledgement PCR message 602.In step 8 716, UE
Stop the ongoing RACH regulation for transmitting the L2ACK PDU co-pending of acknowledgement PCR message 602.Correspondingly, it is based on step
One is related to what is made in two, step 6 can determine to eight, UE and stop for transmit any acknowledgement PCR message 602 to
Certainly any ongoing uplink RACH regulation of uplink RLC ACK PDU.Due to for PCRC message 614
L2ACK 616 is properly received and is executed by UE, is accordingly used in the ongoing RACH of the L2ACK of transmission acknowledgement PCR message 602
Regulation is not necessary and is aborted.

One step 1002, UE 210 from network (for example, UTRAN 202) receive for by UE from the first radio resource control (RRC)
State is reconfigured to the reconfiguration message of the second RRC state.For example, reconfiguration message disposition example can be performed in the processor 804 of UE
Journey 914 disposes circuit system 904 to configure reconfiguration message to receive and handle the PCR message 602 for carrying out automatic network.Moreover, place
RRC state transformation routine 912 can be performed to configure RRC state transfer circuit system 902 so that UE is from Cell_FACH in reason device 804
State is converted to Cell_PCH state.
In second step 1004, UE, which is further transmitted, indicates that the UE disappears to the completion that reconfigures of the transformation of the second RRC state
Breath.For example, executable reconfigure of the processor 804 of UE completes message disposition routine 916 to configure weight in response to PCR message 602
Configuration completes message disposition circuit system 906 with to transmission of network PCRC message 614.PCRC message 614 indicates that UE has been converted to
Second RRC state (for example, Cell_PCH state).
In third step 1006, UE further receives acknowledgement from network, and this reconfigures the first acknowledgement of completion message.For example,
Acknowledgement disposition routine 918 can be performed to configure acknowledgement disposition circuit system 908 to receive acknowledgement PCRC message in the processor 804 of UE
614 L2ACK 616 (the first acknowledgement).In four steps 1008, UE cancels radio link co-pending after receiving the first acknowledgement
Road controls (RLC) acknowledgement (ACK) protocol Data Unit (PDU).For example, RLC ACK PDU disposition can be performed in the processor 804 of UE
Routine 920 disposes circuit system 910 to configure RLC ACK PDU to cancel the L2ACK PDU 620 from RLC buffer.This
Outside, in the 5th step 1010, RLC ACK PDU disposition circuit system 910 can be configured to stop to correspond to the reconfiguration for transmitting
